Abstract

Fault-tolerant communication algorithms for $k$-ary $n$-cubes are introduced. These include: One-to-all broadcasting, all-to-all broadcasting, one-to-all personalized communication, and all-to-all personalized communication. Each of these algorithms can tolerate up to $(2n-2)$ node failures provided that $k (2n-2)$ and $k 3$. Extensions of these algorithms with up to $2n-1$ node failures are also described. The communication complexities of the proposed algorithms are derived when wormholeor store and forward packet routing is used.
